Specification of Letters Patent.

Patented oct. 13, 190s.

Application filed July 31, 1903. Serial No. 167,672.

To all. whom 'it may concern: s

Be it known that we, HARRISON H. EATON and GEORGE GODDU, citizens of the VUnited following to be a full, clear, and exact deV scription of the invention, such as will en-` able others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for making lacing hooks and is intended I' primarily as an improvement on the hook bending machine disclosed in the application of Harrison H. Eaton filed of even'date here'- with.

The machine disclosed in the application above referred to is adapted to bend the body portion of a blank so as to form two curvatures therein angularly `disposed with rela-f tion to each other and the object of the press ent invention is to provide a machine for doing this work of improved and simplified construction, of greater durability, more certain and' reliable in operation, and capable of being operated at a higher rate of speed.

With `this object in view our invention consists in the devices, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

lA hook bending machine embodying our invention in the best form at present known to us is illustrated in-the drawings accom-` panying this application, but it is to be understood that the various features of our invention are not limited except where such limitation is expressed in the claims to the machine illustrated or to any particular construction or. arrangement of parts.

The machine illustrated in the drawings is provided with two bending mechanisms `and with means for presenting a blank successively to said bending mechanisms. The means for presenting a blank to the bending mechanisms consists 4of a carrier in which Vupon by the bending mechanisms.

automatically feeding the blanks to the carrier, the blanks being similar to those illustrated in Figures 2, 3 and 4 of the patent to Harrison H. Eaton for an improvement in lacing hooks, No. 11,874, reissued Nov. 27, 1900. The carrier consists of a disk provided with pockets or recesses to receive the blanks with their body portions projecting beyond the face of the carrier, `and the holding devices for holding the blanks to the carrier during the bending operations consist of disks provided 4with similar pockets or recesses which cooperate with the pockets of the carrier to 'hold the blanks at each of the positions in which the blanks are operated One of the bending mechanisms comprises a bending device which is moved across the face of the carrier and thereby bends the body portion of the blank into a plane substantially at right angles to the axis of the carrier. The other bending mechanism comprises a former which at the proper time during the operation of the machine is moved into a position to be engaged by the body portion of the blank and a bending device which is rotated continuously in one direction about the former and which acts to bend the body portion of the blank around the same.

In order to adapt the machine for bending thebody portion of the blanks to form hooks adapted vto be secured upon either side ofl a lacing slit, or in other words to adapt the machine for forming either right or left hooks, the machine is provided with means whereby the bending device may be rotated about the former in either direction, a right hook being, produced when the bending device is rotated in one direction and a left hook being produced when the bending device is rotated in the other'direction. The specific construction of the mechan- -ism above referred to and of the various parts of the machine will `be understood from the accompanying drawings in which Fig. 1 is a view in side elevation of a hook bending machine embodying our invention in its preferred fornr; Fig. 2 is a view in end elevation thereof looking from the right of Fig. 1; Fig. 3 is a view in end elevation partly in section on the line 2 2 of Fig. 1 looking from the left of said figure; Fig. 4 is a sectional view taken on the line %5, Fig. 1, looking towards the left; Fig. 5 isa sectional View vtaken on the line 4 5,

Fig. l, looking towards the right; Figs. G, 7 and 8 are views on a somewhat enlarged scale illustrating Vthe operation of the plunger for feeding blanks to the carrer,`the operation of the pin for locking the carrier in position and the operation of the bending mechanisms, several of the parts being shown in section in Figs. 6 and 7 to more clearly illustrate the construction; 9 is a view similar to Fig. 5 illustrating a mechanism for rotating the bending device around vthe former in the-opposite direction from that in which it is rotated by the mechanism illustrated `in Fig. 5 Fig. l0 is a detail sectional view illustrating the construction of the former, the bending device vand their operating mechanism; Fig. l1 is a detail sectional view illustrating the mechanism for intermittently actuating the carrier; Fig. l2 is a face view ofone ofthe blocks which are secured to the carrier, Fig. 13 is a sectional view offthe block taken on the line 12S-13 of Fig. 12.; Fig. 14 is a detail view of a blank before it is operated upon by the machine. Fig. l5 is a detail view of the blank as it appears after being acted upon by the tirst bending mechanism and Fig. 1G isa detail view of the completed hook.

Referring to the drawings in which like characters -of reference are applied to like4 parts throughout the several views, l indicates the base of the ymachine frame `from which rise two standards Zand 3 provided with bearings 'for the driving shaft l. Ati one end the driving shaft is :provided with the rfast and loose belt pulleys 5 and G and secured tothe'shaft so as to rotate therewith are vthe'cam disk 7 provided with the cam groove 8, theEperipheralcam t), the cam disk l0 provided withthe peripheral cam groove ll, thefbelt pulley l2, and the gear wheel Projecting upwardly from one side of the standard 3 as ismore clearlyshown in Figs.

5 and 9, is a plate let at the lupper end of which is secured a hopper l5 in which the blanksupon which the machine is designed to operate lare placed. `Leading from Athe hopper l5 is a raceway 16 for the blanks which terminatesin proximity tothe end of the feeding plunger to be hereinafter described, and `which is constructed to present the'blanks in proper position to be fed to the carrierby which the blanks arepresented to the `bending mechanisms. The -blanks lare fed from the hopper into the raceway by suitablemechanism actuated from the driving shaft l by means'of'the belt '17 which passes over the pulley l2 secured to theshaft and over aipulley mounted on the shaftjournaled in the hopper. The hopper and the mechanism for feeding the blanks `from the hopper'to the raceway may be of any suitable or` well-'known construction,-the hopper and'mechanism for 1feeding'the blanks indicated in the drawings'beingthe same'asthat which has heretofore been used in various forms of nailing machines.

rihe carrier t'or presenting the blanks to the bending mechanism is indicated at. 1S and consists of a disk secured to or formed integral with the end of a shaft: ttl journaled in` bearings in the standard 2 above the driving shaft l. As shown the carrier is provided with four pockets or recesses to receive the blanks. These pockets or recesses consist of notches or grooves formed. in blocks lt) set into the recesses in the face of the carrier and slots arranged transversely to the grooves. The notches or grooves in the blocks receive the shanks of the blanks and the body port-ions of the blanks just above the collar at the upper end of the shank, and the slots receive the collars of the blanks, the body portions of the blanks extending beyond the face of the carrier in a direction parallel with its axis. The blocks 19 are held in the recesses in the carrier by means of screws 20.

The carrier 1S is intermittently rotated by the mechanism to be hereinafter described and when at rest one of the pockets of the carrier is in a position to receive a blank which is fed to the pocket by a feeding plunger, another pocketY is in a position to present a blank contained therein to one oll the bending mechanisms and still :mother pocket is in a position to present another blank contained therein to the other bending mechanism. The blanks are fed to the pockets of the carrier 18 by means of a feeding plunger 22 secured to the end of a rod 2) which passes loosely through the rear end of a block 2l and which is provided at its rear end with adjustable stop nuts 25. coiled spring 2o surrounds the rod 23 and is interposed between the plunger and the rear end of the block 2l so that the stop nuts 25 are normally-held in contact` with the rear surface of the block 2l. The block 2l is reciprocated by mechanism to be hereina tter described and the yielding connection between the block 2l and the plunger 22 formed by the spring 26 allows the plunger to yield in case a blank becomes wedged in thelower end of the raceway or in the passageway leading to the pocket of the carrier, the tension of the spring 2o being sutlieient, however, to normally hold the plunger 22 in the position indicated in Figs. t and v7 with relation to the block 2t and to canse the plunger to feed a blank into the pocketv ot the carrier. rl`he block 7l-t and-the plunger 22 reciprocate in a casing formed integral with or attached to the standard 2 ol the frame. The raceway lt extends vertically downward and terminates just above the plunger 22, the lowermost blank when the. plunger 22 isin its retracted position resting upon a ledge or shelf at the inner end otIthe casing in which the plunger 22 and block 21 El t) are mounted. The casing is, cutaway at one side (see more lparticularly Figs. 4 and 8). The `ledge upon which the lowermost blank rests extends in close proximity vto the periphery of the Acarrier A18 and this ledge forms the lower wall vof the passagewayH through which 4the blank is fed by the plunger tothe pocket `of the carrier.` The upper wall of the passageway isV formed by the lower end yof lthe yraceway A16 and the shaped to receive the collar of the'blank.

The carrier 18 is rotated through a'q'uarterl of a revolution to bring the blank which has been fedi-nto Ione of the pockets. into aA position to be acted upon by the irst'bending mechanism. `When thevblank is in this position it is'lield in the carrier by means ofl one `of a series ofholding devices formed in or-carried by a .disk 28A secured to or formed integral with oneend of a shaft mounted in bearings above -the shaft 192L of the carrier 18. As shown the holdino'devices consist of blocks 29similar to the blocks 19 secured in recesses in Athe disk 28, 'these blocks being provided :with grooves and slots similar .toA

those in the blocks 19. The disk 28 is actuated simultaneously with the carrier 18 as will be hereinafter-described and the blocks 29are so arrangedthat the grooves and-slots therein will successively engage theV blanks in the pocketsof the carrier as the pockets are successivelybrought into position to present the `blanks `therein tothe action of the first bending mechanism. After the blan-k has been acted upon by the first bending mechanism the'carrier is rotated a quarter of a revolution to bring the blank intov a position to be operated upon bythe second bending mechanism. .During `this movement of `the carricrithe blank is held in the pocket of the carrier by means of av curved plate 30 similar to the plate 27. Vhen the carrieris in `position'to present the blank tothe action of the second bendingmechanism, the blank is held `inthe` carrierby means of holdingdevices consisting of blocks 31 similar to the blocks 19 and 29 secured in recessesin a disk 32 secured to or formed integral with ythe end of a -shaft vmounted yin `bearings'at one side ofthe shaft 19a of the carrier 18. The

to be operated upon'by7 -the second bending mechanism. The bearings for'the shafts for the'disks 28 vand 32 are carried by plates `33 and 34 adjustably secured to the standard 2 `ofthe lmachine frame by means of clamping screws 35 and `stop screws 36 whereby the ldisks 28 fand 32 `.maybe adjusted towards and from the disk 18 as maybe desired.

The carrier 18 is Aintermittently rotated from the cam. groove 8 of the cam disk 7 upon the main driving Vshaft land `the `disks 28 and. 32 are rotatedsimultaneously with ythe vcarrier :18 by mechanism which may be ldescribed `as followsrTo the outer end of fthe shaft 19a of the carrier 18 is secured a disk 37 provided with four notches with which a spring-pressed pawl 38 is arranged to engage. The pawl 38`is mounted upon :a `disk 39 loosely mounted upon the outer -end of the shaft 19a. vided with a flange projecting over the disk '37 and upon its lowerledge is provided with va series of gear teeth 40 meshingwith a :series of gear teeth 41 uponthe lupper end 5of a lever 42.

The disk '39 Vis pro- The lower end of the lever 42 is pivoted at 43 to the standard 2of1the the disk 37 (see Fig. 11) and gears 46 and 47 meshing with the f gear 45 are secured to the shafts of the disks 28 and 32, whereby the disks 28 and 32 are rotated intermittently simultaneously vwith the carrier 18.

In order to stop the'carrier 18 in a proper position to presen'tthe blanks inthe pockets thereof to the bending mechanisms, and in order to positively prevent the carrier from mentum of the various parts, a stop disk 48 issecured to the outer end of the shaft of the disk 28 which disk is provided with four notches one of which is engaged by an arm 49, secured to the disk 39, at the end ofthe movement ofthe disk in the direction in which it is `connected to the shaft of the carrier 18 by means ofthepawl 38.

During'the operation of the bcndingmechanisms ythe carrier ,18 yis positively locked in position by means of a 'locking kpin 50 (see .more particularly Fig. 6). Thispin is mounted to reciprocate in a casing vattached to or formed integral with the standard 2-of theimachine frame and is provided with a projection `which isadaptedfto enter notches 51 in the periphery ofthe carrier when the pin is moved toward the carrier. The lpin Vis forced toward the carrier by means lof a coiled spring 52, one end of whichis seated in a recess lin the "lowerend of the pin, and the-other end fof which is being moved beyond this position by the mo seated in a recess in a cap 53 having a screwthreaded engagement with the lower end ot the casingin which the pin is mounted. rlhe pin is retracted to release the carrier and to allow itto be rotated, by means of a bell crank lever 54, one end of which is provided with a roll 55 bearing upon a cam 9, and the other end of which projects through a slot in the casing in which the pin 50 is mounted and is provided with gear teeth meshing` with a series of teeth upon the pin.

In the machine shown in the drawings, the movement of the locking pin 50 is utilized to actuate the plunger Q0 which Yfeeds the blanks into the pockets of the carrier and to this end a lever 55X is provided, the two ends of which are provided with gear teeth which mesh with gear teeth upon the locking pin 50 and-block 24 respectively. As a further means for insuring the proper actuation ot the carrier, the machine shown in the drawings is provided with a friction brake 5G which is pressed against the periphery of the disk'QS by means of coiled springs 57 surrounding` guide rods 58 upon which the brake is movably mounted and being interposed between lianges at the upper ends ot the rods and the brake.

The means for bending the body portion of the blank consists of two mechanisms, one of which is arranged to bend the body portion of the blank at an angle to the shank. and the other of which is arranged to bend the body portion of the blank to form therein a curvature angularly disposed with relation to the first curvature. The lirst oi these bending` mechanisms is arranged to act upon the blank which is held in the carrier by the holding devices on the disk 2S and the second of these bending mechanisms is arranged to act upon the blank which is held in the carrier by the holding devices on the disk Both of these bending mechanisms act while the carrier is stationary, the bending mechanisms and the carrier being so arranged that the carrier presents the same blank successively and different blanks simultaneously to the bending mechanisms. After ay blank has been ted into a pocket of the carrier and the carrier has been rotated through a quarter of a revolution, the blank is held by one of the holding devices on the disk 2S with its body portion projecting beyond the carrier. The bending mechanism for acting upon the blank while so held consists of a roll 59 journal'ed in the forked end of a bent lever (30 pivotally mounted upon a stud 6l secured in a split clamp on the standard 3 of the machine rame. lThe lower end of the vertical arm of the bent lever G0 is provided with a roll which engages the cam groove 11 of the cam disk l() secured to the driving disk 4. By means of the cam groove 1l the lever G0 is oscillated at the proper time during the operation of the machine and the roll 59 is moved across the tace ol the carrier '1S thereby engaging the body portion olE the blank projecting ilrom the carrier and bending ity into a. plane substantially parallel with thc liace o'l, the carrier. The stud (l upon which the lever is pivotcd is provided with an eccentric portion, whereby the position olf the roll 59 can be. adjusted as desired by rotating the stud and clamping it in the desired position. After the body portion olf the blank has been bent by the action ot the roller 5S) as described, the carrier is rotated through another quarter ot a revolution and the blank is brought into a` position to be acted upon by the second bending mechanism, being held in the carrier when in this position by means ot one oit the holding devices on the disk 32. While, the blank is being transferred irom the position in which it is acted upon by the Vlirst bending mechanism to the position in which it is acted upon by the second bending ineclianism the body portion oli the blank is held in the position into which it has been bent with relation to the. carrier by the engagenient therewith o'll one of four holding pins 80, one ot these pins being yieldingly mounted in each block lf) and being provided at its outer end with a groove to engage the body portion ol a. hook as is clearly illustrated in Figs. 1Q and 13. The second bending mechanism comprises a t'ormer (32 (see more particularly l `igs. 5, S and 10) and a bending' roller or stud 'l`hc former (SQ. is provided with a shank which has a driving tit in the end oli a longiludinally movable plunger (H- (scc. more pal'- ticularly Fig. l0), the plunger being provided with a transverse ju\.i"l'oration (35l into which an implement can be inserted a'lilcr the plunger has been removed trom thc. machine, it it is desired to remove. the toi-mer Ytrom the plunger. The bending roller or stud (39 is mounted upon or secured to the end olil a sleeve ($5 mounted in a` bearing inV the upper end of the standard 3. The plunger (tl cxtends axially through the sleeve (15 and that portion ot they plunger in contact with the. sleeve is cylindrical in order to allow the sleeve to rotatie without rotating thc plunger.

The plunger G4 is'mounted to reciprocate `longitudinally to bring thev former 62 into a position to be eiigagedbyV the body portion of the blank andV to be` withdrawn from such. position after the body portion ofv the blank has Abeen jbent around the same to allow Athe completed hook to drop out of the `machine during the con tinued rotation ofthe carrier.

cured thereto and the disk is provided'with a p'eripheral cam groove 70 which is engaged by a pin 71 secured in a split clamp projecting from the face of the gear 68, the

construction being suoli that the plunger 64 is ijeciprocated during the rotation of ythe gear '68 by the engagement of, theV pin 71 with tliecam groove 70.` The plunger 64 is held from rotation by means of its squared rear end' which is received in a giiideway1 formed in the upper'overhanging end of a standard 72 rising `fromthe base oftheniachine frame.

The manner yin which the body portion oi' the blank which has been bent into a Vplane- Ybody portion of the blank around the former.

1t will be noted that the former G2 is arranged ecceiitrically with the axis about The result of this relative arrangement of the former and bending device is that the bending device engages, the body portion of the hook near the outer end and thus acts to the best advantage in bending the body portion of the blank around' theY former. As the bending device passes otf kof the end of the blank it is moving away from the former and does not press the blank `forcibly against the former so as to produce a bur on the end of theblank. V

After the body portion of the hook has been bent around the former-as above described, the former is withdrawn and the carrier is again rotated through a quarter of a revolution. During such rotation the hook which has been completed drops out of the pocket in the carrier into a chute 73 and is delivered from the machine.

If it is desired to bend the body portion of the hook about the former in the reverse direction to that illustrated in Fig. 8 in order to produce a hook adapted to be secured to the other side of the lacing slit, the mechanism illustrated in F ig. 9 is utilized, an intermediate gear 74 journaled upon a stud secured to the standard 72 being provided, the gear meshing with the intermediate gear 74 and the intermediate gear meshing with the gearl. The bending device 63 is thus rotated about the former 62 For so re-y ciprocating the plunger 64 Ya disk69 is Ysein the opposite direction.- When the arl rangement illustrated in Fig.` l is used the lposition. of the former and the bending-device will bechanged as Aillustrated in saidv ligure.

lThe operation of the machine illustrated in the drawings `has been 'indicated in con-` nection with 'the description ,of the construction, and willbe readily g'imderstood. A

separate description thereof' is therefore deemed unnecessary. Y

Having thus indicated terredform thereof, VVwe claim as new and desire vto secure by Letters Patent of the United States. l
